Dear Kostas,
The dal::dynamic_tree_sorted implements an array with a sorted index. It is
closed from std::map. The difference is that the values are stored in an
array. It is an old implementation (1995). At that time the STL was not yet
stabilized and available on all implementations ! (In fact I did not know its
existence when I programmed dal::dynamic_tree_sorted).
Normally, it is stable. It is used in several algorithm in getfem. So, i am a
bit surprised that it does not work ... !
However, the use of dal::dynamic_tree_sorted should be avoided now and
replaced by the use of a std::map. So, if it is working with a std::map,
please commit your changes.
Regards,
Yves.
